SPIDER: Searching for the echoes of inflation from atop the atmosphere
Balloon-borne platforms have long served as a shortcut to space-quality science and as pathfinder instruments for satellite missions. NASA's Long Duration Balloon platform allows for flights lasting roughly 20 days, carrying payloads weighing upwards of 6000 lbs. Spider is a balloon-borne microwave polarimeter that aims to take advantage of this platform to obtain very high sensitivity maps of the polarized cosmic microwave background, over a 10% patch of the sky and at 3 different frequencies -- 95, 150, and 285 GHz. The spatial and frequency coverage should allow for effective separation of foregrounds from the signal, potentially reaching an upper limit of r < 0.03.
Designed as a two-flight mission, Spider completed its first flight in January of 2015 after a 16 day voyage, suspended 36 km over the Antarctic continent. During the first flight, Spider observed a high Galactic latitude patch of the sky with over 2,000 polarization sensitive bolometers at 95 and 150 GHz. The second flight will replace some of the receivers with three high frequency 285 GHz channels containing 512 channels each. I will go over some preliminary results from the first flight, discuss some of the challenges involved, and motivate the need for a second flight. I will also give an update on the status of preparation for the second flight, which is scheduled for the end of 2018.
